if consumers find that businesses are infringing or fraudulent when shopping, they can defend their rights according to law, but they also need to go through legal procedures to avoid extreme behavior, so where can 315 complain? Let's take a look at it together. 1. Where to complain at 315? The telephone number for specific complaints is: local area code plus 12315. Consumers are treated unfairly, or the products they buy are wrong (false or damaged), and they can't get an effective response from the merchants, so they can call the hotline 12315 of 315 (consumer protection organization) to make a complaint. At present, the departments that accept product quality problems in China include the administrative department for industry and commerce, the quality and technical supervision department, the consumer association, the competent department of enterprises, the commodity inspection department and the people's court. In terms of product quality supervision and inspection, the State Council has a clear division of labor between the State Administration for Industry and Commerce and the State Bureau of Quality and Technical Supervision as follows: (1) In the field of production and circulation, the State Bureau of Quality and Technical Supervision and its subordinate quality and technical supervision institutions at all levels are responsible for investigating and handling product quality responsibility issues; Where assistance from the administrative department for industry and commerce is needed, the administrative department for industry and commerce shall cooperate. (2) Illegal acts of producing and distributing adulterated products and counterfeit products found in market management and trademark management shall be investigated and dealt with by the administrative department for industry and commerce, and the quality and technical supervision department shall cooperate with them. (3) Any act of reselling or fraudulently selling inferior commodities in the market that is discovered by the administrative department for industry and commerce shall be investigated and dealt with by the administrative department for industry and commerce; Need the assistance of the quality and technical supervision department, the quality and technical supervision department to assist. What is found by the quality and technical supervision department shall be investigated and dealt with by the quality and technical supervision department; Where assistance from the administrative department for industry and commerce is needed, the administrative department for industry and commerce shall provide assistance. The same problem shall not be dealt with repeatedly. 3. What evidence should consumers keep? In the face of repeated bans on fake and shoddy goods in the market, consumers must ask for evidence of consumption after purchasing and consuming goods. Evidence of consumption includes four aspects: invoice, warranty card, certificate of approval and product description. In this regard, consumers must ask for it and keep it properly. Invoice-a document in the form prescribed by law stating the payment of a certain amount of money. The form and content of invoices must be effective, which is the first condition for administrative, judicial organs and consumer associations to accept complaints. The contents of the invoice include the real names of the operator and the customer, the time of the shopping day, the product specifications, quantity, price, the official seal of the operator, and the signature or seal of the agent of the sales unit. If the bill provided by the merchant is irregular or has no official seal, it should be rejected. Warranty card-a certificate to facilitate consumers to repair products. Non-perishable goods should be accompanied by this card. Once there is a problem with the product, consumers should go to the warranty unit designated by the manufacturer for repair, and the maintenance unit should accurately record the repair time, repair items and names of the repairmen on the warranty card, which is the biggest blind spot for many consumers to lose reasonable compensation when their rights and interests are infringed. Certificate of conformity-a certificate that proves that the quality of a commodity meets the design and manufacturing standards and has passed the inspection. It is an important certificate to measure the quality of goods, and all non-perishable goods should be accompanied by this certificate. In particular, the certificates of household appliances, motorcycles, computers and other large items are particularly important to ensure their safe use. Consumers should take the initiative to find and pay attention to preservation when purchasing. Instructions for use-normative materials detailing the usage and precautions, such as electrical appliances, machinery and computers, should be attached. The above is the details about where to complain about 315. According to the relevant provisions of the law, if consumers have disputes with businesses, they can call the consumer rights hotline to protect their rights.
